    At the time of their introduction, other than being based on a cut down 10mm casing, what did the .40 offer that the .41 didn't? The .41 beat it to the market by 4 years, uses a standard 9mm bolt face due to it's rebated rim which aids caliber conversions and I could be wrong, but aren't they basically ballistic twins? Other than the backing of an industry giant is there any reason the .40 thrived and the .41 died?

    Nope, that was pretty much it. S&W still had the majority share of LE firearms contracts in the US. The FBI and other LE agencies were figuring out that the 10mm was a bit more than they bargained for, and dificult for some smaller statured officers to fire and control. S&W developed a product to fit the need/desires of their major customer base. They marketed it well, pushed it well, and had a ready market to push it out to. Gun manufacturers could used some of the barrel manufacturing equipment due to same bore diameter, just a differerent chamber depth.

    Makes sense. The choice of a .40 caliber bullet in the 10mm has also always bewildered me as the last cartridge to be a .40 cal was the .38/40 when the .41 Magnum had been released much more recently.

    But, they needed to make use of the 10mm bullets that had already been developed.

    Eh, we got a few decent rounds out of the 10mm. 10mm, .40 S&W, .357 Sig once they necked down the .40.
